Old A6 with 6-7psi. The BTM ended up set on 0 all the time.

 

Hang out with domestic guys. They sell old electronics, BTMs, etc, for pennies compared to the import guys.

 

Where did you get that for $40 dollars ?

 

Do you think 10psi of boost on a B16A1 requires the use of a BTM?

And BTW,how do you fit a BTM and more important for me:how does it work

 

You take the two wires on the coil wire them to the two wires going into the MSD Box and there should be another two wires I think red and black and wire them where you old coil wire used to be and drill a hole in the side of the cap so the old wires can come out and the new ones in.... basicly re-routing the positive and negitive wires so the MSD controls the spark not the car. Then just hook a vacuum line up that sees boost to the MSD port on the side of the box. Now when the boxs sees boost it retards it per what you set the *** at ( i.e. .5 per pund of boost ). Basicly I believe thats it.... There's a article about how-to wire it up in the FAQ post in one of the other forums just look for it. I just don't like the fact that you have to drill into the cap.

 

Hey,it sounds good...
